WINDOW ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 681 ,437, dated August 27, 1901.

Application filed January 11, 1901. Serial No. 42,832- (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. BERBERICH,

a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Window Attachments, of which the following is a full and complete specification, such as will enable those skilled in the art to which it a'ppertains to make and use the same.

This invention relates to attachments for Window-sashes; and the object thereof is to provide an improved device of this class which is adapted to be connected with one of the sashes and to operate in connection with both, whereby the sashes may be locked in a closed position and either or both of said sashes locked in an open or partially-open position and with this and other objects in view the invention consists in a device of the class specified and constructed as hereinafter described and claimed.

The invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same reference characters in each of the views, and in which- Figure 1 is a front view of the windowframe and the sashes mounted therein and showing my improvement connected with the upper sash and said sash partly lowered; Fig. 2, a partial vertical section through the frame and sash, taken on the line 2 2 of Fig. 1; Fig. 3, a view similar to Fig. 2, showing the sashes locked in a closed position; and Fig. 4, a sectional view of the detail of the construction which I employ.

In the drawings forming part of this specification I have shown at 5 a window-frame, and at 6 and 7 the upper and lower sashes, which are mounted therein, and in the practice of my invention I provide a device of the class specified which consists of a verticallyarranged rack-bar 8, the teeth of which face inwardly and are preferably countersunk, and the said rack-bar is angular in cross-sec"- tion and provided at its upper and lower ends with a transverse plate 9, and by means of these transverse plates 9 the rack-bar may be secured to one of the sashes, and in the accompanying drawings the said device is secured to the upper sash.

The rack-bar 8 is angular in cross-section, except approximately at the lower end, where it is cylindrical in cross-section, as shown at 10, and mounted on said rack-bar is a vertically-movable sleeve or slide 11, also angular in cross-section and which is provided at one side with a downwardly and forwardly or provided with a longitudinal chamber 13, through which passes a shaft or pin 14, on which is mounted a spring-operated catch 15, provided with side jaws 16, through which the shaft or pin 14 passes, and wound on said shaft or pin .is a spring 17, provided with a projection or finger 18, which bears on the bottom of the shoe 12.

The catch 15 consists of a metal plate, one end of which projects downwardly and for wardly to form a finger-piece 19 and the other end of which projects upwardly and in the direction of the rack-bar, so as to form a lockin g-lug 20, which operates in connection with the teeth of the rack-bar 8, and passing loosely through the top portion of the spring-catch 15, above its pivotal support, is a screw 21, which passes through one side of the sleeve or slide 11 or may pass therethrough, and this screw is adapted to operate in connection with a transverse notch or recess 22, formed in the front side of the rack-bar 8, below the teeth thereof. 1

The sleeve or slide 11 may be moved vertically on the rack-bar 8, and in the normal position of the parts the locking-lug of the spring-operated catch 15 is held in engagespring 17, as shown in Fig. 2, and the opening 23 in the spring-operated catch 15 through which the screw 21 passes is large enough to permit of the operation of said spring-operated catch without moving the screw21, and by depressing the finger portion 19 of said spring-operated catch the sleeve or slide 11 may be moved vertically on the rack-bar, as will be readily understood.

The shoe 12 of the sleeve or slide 11 is adapted to bear on the bar of the upper sash, as shown in Fig. 1, when it is desired to adjust or open the upper sash, and it will be apparprojecting shoe 12, the top of which is open ment with the teeth of the rack-bar by a cut that in this position of the attachment or the separate parts thereof the lower sash may also be adjusted, and when it is desired to lock the sashes together in a closed position the sashes are closed and the sleeve or slide 11 is moved down below the cylindrical portion 10 of the rack-bar 8 and the screw 21 is screwed into the notch or recess 22 in the lower end of the rack-bar.

In order to move the sash vertically to the farthest extent and without interference of the attachment, the sleeve or slide 11 is moved onto the cylindrical portion 10 of the rack-bar 8 and into the position shown by the dotted lines in Fig. 1, and in this position of the attachment or movable member thereof the sashes may he raised and lowered to the farthest extent the same as though the attachment were not employed. The screw 21 may also be used to secure the slide or sleeve 11 at any point on the rack-bar 8, as shown in Fig. 2, so as to regulate the relative positions of the sashes in the adjustment thereto.

By means of my improved window-sash attachment the windows may be locked together in a closed position, as ordinarily; but they may also be locked together in such position of either one or both windows that the sashes maybe opened a slight distance at the top or bottom to permit the entrance of air to ventilate the room, and while both. sashes may then be moved together upwardly or downwardly such slight distance they yet will be locked securely and will prevent the entrance of any person through the windows, it being manifest that both windows must be closed before the attachment can be unlocked, as the sleeve or slide must descend to the cylindrical point upon the rack-bar before it can be turned. It will be apparent that changes in and modifications of the construction may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An attachment for window-sashes, comprising a rack-bar which is angular in crosssection and adapted to be secured to the side of one of the sashes, said rack-bar being provided near its lower end with a cylindrical portion, and with a sleeve or slidewhich is mounted thereon, and which is provided with a projecting shoe open at the top and provided with a spring-operated catch which is adapted to engage the teeth of the rack-bar, substantially as shown and described.

2. An attachment for window-sashes, comprising a rack-bar, which is angular in crosssection and adapted to be secured to the side of one of the sashes, said rack-bar being provided near its lower end with a cylindrical portion, and with a sleeve or slide which is mounted thereon, and which is provided with a projecting shoe open at the top and provided with a spring-operated catch which is adapted to engage with the teeth of the rackbar, and a screw which passes loosely through said catch and through one side of the sleeve or slide, and which is adapted to engage the rack-bar, substantially as shown and described.

3. An attachment for a window-sash, comprising a rack-bar which is adapted to be secured to one side of the sash and which is provided near its lower end with a cylindrical portion, and below said cylindrical portion with a notch or recess, and a slide mounted on said rack-bar and provided with a projecting portion or shoe, a spring-operated catch mounted in said projecting portion or shoe and adapted to engage the rack-bar and means for locking the slide to the lower end of the rack-bar, substantially as shown and described.

4:. An attachment for window-sashes comprising a rack-bar which is angular in crosssection and adapted to be secured to the side of one of the sashes and said rack-bar being provided near its lower end with a cylindrical portion and with a sleeve or slide which is mounted thereon and which is provided with a projecting shoe, a screw upon the same for looking it upon the rack-bar, the said screw passing through one side of the sleeve or slide and being adapted to engage the teeth of the rack-bar.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 9th day of January, 1901.

CHARLES A. BERBERICH.
